The Sunsynk Three-Phase Hybrid Inverter is a highly efficient power management tool for three-phase grid applications. This inverter allows the user to control power flow from multiple sources such as solar, main electrical grids, and generators, and effectively storing and delivering the power when required. They can operate with unbalanced loads, which means you can have 20% connected to one phase, 20% to another, and 60% to the third phase, and it still gives perfect phase rotation. There is no other inverter in their class that can offer this amazing feature. Features: 48V low-voltage battery. Isolation transformer design. 6 time periods for battery charging/discharging. Maximum charging/discharging current of 240A. Frequency control. Up to 10 inverters in parallel. DC and AC couple to retrofit the existing solar system. supports generator connection. Interactive display. 5 year warranty
